Specification of LettersPatent No. 32,193, dated April 30, 1861. l

. To all `'whom 'it may concern:

Be it known that I, FREDERIC KETTLER, of Milwaukee, lin the county of Milwaukee, in the State of Wisconsin, have invented new and useful Improvements in Machines for Cutting, Boring, Splitting, and Taking Up Stumps and Roots for the Purpose of Clearing the Land; and l do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being hadto the an' nexed drawings, making a part of this specification, in which- Figure 1 represents a side view of the whole apparatus. Fig. f2 represents a plan or top view of the same. Figs. 3,4 and 5 represent the cutting tools, hereafter to be described.

Similar characters refer to like parts.

A is the main frame work and P the standards to sup ort the machinery; p vertical slide pieces fastened to the standards P.v

A2 is a frame for supporting the boring and splitting or cutting machines. Said frame A2 is intended to slide up and down in the slide pieces 79 of the standards P so as to regulate the proper position of the machinery which it supports.

R is the boiler, secured firmly to theframe A', F two rotary steam engines which are secured by bolts to the mainframe A and standards P. 4

p2 are the steam pipes; G, G and G the wheels to support and carry the whole apparatus. In Fig. 1 one of the side wheels G is not drawn for the purpose of showing the inner parts ofthe apparatus better.

B is the main driving shaft, which is double at a and a.

a and a` 'are two hollow. shafts, marked freely on the shaft B and in the rotary steam engines F.

D aretoothedwheels attached on the outer ends of the hollow shafts a and a.

m3 represents a disk with inserted pistons fastened by means of a key or setscrew on shaft B so as to put them in or out of work. The conical wheels I and H are in gear. The wheel I, pulley c and crank efare se- `cured on the vertical shaft J which works inside the frame A. The `crank e serves to work a saw to cut the stump shorter.

M and d is a double shaft. M is the outer or hollow shaft which is fastened to the frame A.

f are two boxes .Xed within the shaft M to receive the inner shaft d. The :shaft M being also stationary and shaft cl works freely in boxes f of shaft M.

The cranks g, the wheels E and wheels c3 are fixed on the shaft 0l. Motion is imparted through the wheels E. 'Crank g works also a saw to shorten stumps.

m are two grooves cut in the hollow shaft M, so as to allow the chains l) to work freely.

a is a top piece secured on the standards P.

L is a vertical shaft which works in the center between the standards P.

g, r, s and 02 are pulleys on the shaft L. The pulleys c and c2 are worked by means of a chain.

N and K is a double shaft; K the outer shaft being hollow and working freely in boxes t of the frame A2. N is the inner shaft `with a socket at its lower end.

g2 is a pulley and a a bore; the first being secured on the top of shaft N and the latter fixed in the socket of the lower end.

K2 is an arm for- .supporting the cutting and splitting machine. One end of this arm K2 is secured on the hollow shaft K under an obtuse angle.

s2 is a loose pulley on the hollow shaft K.

The pulleys Q and g2 are worked by a belt. The' pulleys Q, r ands are larger than the pulleys g2, r2 and s2 so.as to increase the speed of the cutting or splitting machines. In case less speed should be required, the

pulleys s2 and roller C may be connected with a belt.

It is understood that the inner shaft N works freely in the hollow shaft K.

B2 is a double wheel with two sets of teeth, loose on the hollow shaft .K. Said wheel B2 is fastened to the frame A2 when the boring and cutting or vsplitting machine is in operation.

R2 is the stump which is'partly `cut as is y shown in red.

O is a square block with a horizontal hole in the center; it is fastened on the Varm lhaving teeth so as to be worked up and down by the wheels a3 and c2.

y and y2 are plates that bind the forked pieces together.

z and z2 are two brackets; thefirst one being firmly attached on the arm K2 of the hollow shaft K and the latter to the block O.

1, 2 and 3 are parallel shafts which work in boxes of the brackets e and z2 and forked pieces v and v2. y

4, 4 and 5, 5 are two sets of parallel rods,

movable on the shafts 1 and 3 and connected by a little parallel shaft i is a wheel and lc a pulley on the shaft 1 which gives motion to the pulleys of shaft and the pulley and wheel X on shaft 3. The pulleys are operated by belts X the splitting machine, see Fig. 1, is a conical wheel in the outer rim of which stonecutters chisels are screwed. Those stonecutterschisels project three different ways as is ,shown in the diagram. The split-` ting wheel may be replaced by a chain-saw, see Fig. 3, in which case a pulley Z is fastened on shaft 1 and another pulley 0 of the same size on shaft 3. The teeth of the chainsaw are-in the same direction as the chisels of the wheel X. The saw in Fig. 4 or planing machine in Fig. 5 may be used instead of the conical wheel X, according to circumstances.

Itis obvious that the conical wheel X, the savvsinHFigs. 3 and 4 and the planing machine in Fig. 5 will'cut the stump conically when the arm K2 makes its revolution around the shaft or bore N.

S is a crane with a catch T, fastened on the top of the boiler R and top piece n. This crane serves to raise or lower the boring and cutting or splitting machines, also for lifting the stumps.

Fig. 4 represents a forked piece to which a saw is attached; this saw is intended to be worked up and down by an eccentric U on shaft 1.

Fig. 5 represents two views of a planing machine for paring or planing away the stu1nps5'this planlng machine consists of two rows of chisels fastened on a plate, when in operation it is fastened to the forked piece v2 and goes on shaft 3.

V is ahorizontal bore with a pulley fastened on the end; it is operated with a cross belt from pulley C. This bore V is about four or five inches in diameter and is calculated for splitting and boring the stumps.

The wheels C3 are provided with a chain for pulling the stumps after being split.

W are curved armpieces to tear and cut the roots; they are hung with pins Z3 in suspending brackets Y. The arm-pieces WV are provided with teeth similar to those of a saw, with the exception that their edges are sharp on both sides. Said arm pieces will revolve vas soon as the carriage is in motion.

Z is a box with cutters on one end and serves to clear the land of roots, weeds, &c. This boX is suspended by rods Z2 to main frame A; its cutters are constructed in the same manner with teeth as the arm-pieces lV, they serve also to cut the roots.

Operation: As soon as steam isadmitted to the rotarysteam engines or cylinders F, the disk m2 with its inserted pistons, as described in my claim of Oct. 1860, will r'e- -volve and move the wheels D fastened on the same hollow shafts a and a. The teeth of wheels D will mesh into the teeth of wheels D2 and cause them to revolve. The wheels D2 being secured to' the carriage wheels G these latter will revolve also in the same time and move the carriage. It is obvious that the carriage is steered by the rotary engines F. The armpieces W will revolve by the motion of the carriage to tear and cut the roots, and throw them in the box Z which latter will clear the land entirely. The shaft B is operated by screwingthe hollow shafts a and a to it. The wheels E, roller C and conical wheel H will then revolve being fastened on shaft B. The teeth of the conical wheel H will mesh into the teeth of the pinion I and move it around. Shaft J, vpulley c and crank e will receive rotary motion through the pinion I. The pulley c gives motion to the pulleys g, r, s, 02 and crank L of shaft L, these latter pulleys working the pulleys Q2, r2 and s2 of shafts N and K. As soon as the apparatus is moved on its wheels G, Gr and Gto the desired place the wheels D will be put out of gear, so that the apparatus will stand still. The bore N is then applied about two inches deep in the center of the stump so as to give a steady point to the arm K2 with its cutting tools to revolve around. The pulley Q2 will be then loosened and the double toothed wheel B2 fastened to the slide frame A2. The hollow shaft K with its arm K2 will be revolved by pulley r2. The wheel z' of shaft 1 and wheel j of shaft 2 will revolve around 'the teeth of the wheel B2 from the left to the right as soon as the hollow shaft K turns around and will impart motion by means of shafts 1 and 2 to the pulleys ofthe shafts a2 m and 3. By this motion the cutter is carried around the base of the stump and the feed thereof being effected by the forked pieces above described, the stump is cut or notched to any desired depth..

Having thus fully described Jche nature of niy invention, what I claim therein as new and desire to secure by Letters Patent is l. The use of the borer V, represented in Figs. l and 2, employed for the purpose of splitting the stumps.

2. The splitting or cutting Wheel X in Fig. l, which Will eut the stumps eonieally to any desired depth.

3. The chain-saw in Fig. 3 Which is carried around by the rollers or pulleys l and 0,

to out the stumps conically to any desired depth.

4;. The planing 0r paring machine in Fig. 5, which is operated by the forked piece@2 and shaft 3 which machine is used for the purpose of paring or planing away the stumps conically to any desired depth.
